SINGAPORE - The unemployed woman who allegedly hurled a bottle of chilli sauce out of her 16th-storey Sengkang bedroom window - and has another killer-litter charge pending against her - has been denied bail and the chance to go home.

Instead, Thiang Ai Lian, 34, now faces two new charges of abusing police officers and will remain at the Institute of Mental Health (IMH).

Prosecutors applied for her to be remanded a further two weeks for psychiatric assessment, after her unsuccessful plea to District Judge Shaifuddin Saruwan to let her be with her cancer-stricken mother.

Defence lawyer Louis Lim told the judge that Thiang's mother and sister "would like her to be at home to support her emotionally", while her boyfriend also vouched in court that she would keep all her IMH appointments if bail were allowed.

But a police prosecutor said the first round of psychiatric tests had proven inconclusive and that IMH's doctors needed more time.

He added that an IMH report cited Thiang for being uncooperative since Dec 13, the day she was arrested and placed in remand, and for refusing to take her medicine.

The court also heard that she was, in fact, not living with her mother.

Doctors also stated in a report that interviews with Thiang's family members had revealed she was not on talking terms with her sister.

In rejecting the bail application, DJ Shaifuddin said Thiang had "shown history of disorganised behaviour and was uncooperative" at IMH.

The bespectacled woman with shoulder-length hair, who smiled and gestured to her boyfriend when she was in the dock, turned visibly distraught when the judge ordered her to be remanded further.

Thiang will be back in court on Jan 19.

Any person convicted of throwing killer litter may be fined up to $2,500 or jailed for up to six months, or both.

The Housing Board can also acquire a flat or terminate the tenancy of a rental flat if residents flout this law. - TODAY
